LEWIS II. ROCKAFELLOIV, OF PHILADELPHIA, PENNSYLVANIA.

KEY-TURNER FOR GAS AND ELECTRIC LIGHTS.

SPECIFICATION forming part of Letters Patent No. 443,543, dated December 30, 1890.

Application filed January 17, 1890- Serial No. 337,256- (No model.)

To all whom, it may concern.-

Be it known that I, LEWIs H. ROCKAFEL- LOW, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Key-Turners for Gas and Electric Lights, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a device for turning the keys of gas or electric lights, the same being adjustable to different locations of such keys.

Figure 1 represents a side elevation of a portion of a key-turner embodying my invention. Fig. 2 represents a longitudinal section thereof.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings, A designates the fork or crotch of a key turner, the same being attached to a rod or tube B, which latteris connected by a gimbal or universal joint 0 with a rotary sl1aftD,which passes freely through the tubular handle E, and has at the'lower end a knob or button F for operating purposes. The rod or tube Bis fitted within a tubular guide G, which is encircled by the clamping-collar II, to which is pivoted one end of an arm or stay J, whose other end is pivoted to a clampingsleeve K, fitted on the upper end of the tubular handle IE, it being evidentthat said sleeve K may be raised and lowered, in which case the arm J follows the motions thereof, and the fork A may be placed in upright, lateral, or horizontal and intermediate positions, so, as to be applied to keys or cocks that may be arranged at the bottoms, sides, the, of gas or electric-lightfixtures. In the adjustment of the fork the joint C intermediate of the rod or tube B and shaft D, owing to its articulation or service as a tumbler, permits said rod or tube, with the connected parts, to change its angle, whereby the fork may be set in the desired position, as has been stated. hen this is accomplished, the sleeve K is tightened on the handle E by the screw I. thereof, and thus the-fork retains its adjustment. The fork is then fitted on the key and the knob or button F rotated, whereby motion is imparted to the shaft D, thejoint O,and the rod or tube B, so that the fork rotates and the key or cock is turned. The tube G, which forms a guide and bearing for the rod or tube B, may be dispensed with, in which case the rod or tube B is adapted to rotate within the collar H as the guide and bearing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,is

1. A key-turner having a fork, a two-part rotatable shaft, a universal joint connecting the parts of the shaft, and an adjustable supporting-arm which engages the respective parts of the shaft, and having clamping end to permit the adjustment and support of the forked part of the shaft, substantially as described.

2. A key-turner consisting of a fork, a retatable shaft, and a universal joint connecting said fork and shaft, bearing for said fork, a handle for said shaft, and an adjustable supporting-arm connected with said bearing and handle, substantially as described.
